Abstract (en)
[origin: US4981536A] The present invention concerns propellant compositions for the generation of nontoxic gases which are utilized, for example, in airbag generators. These compositions contain, as a gas-yielding component, at least one alkali azide. According to the invention, the compositions are stabilized against the effects of moisture and carbon dioxide by the addition of talc and/or magnesium oxide. These additives are included in amounts of from 3 to 10% by weight. The additive acts so that the propellant compositions do not release hydrazoic acid even under the action of moisture and/or carbon dioxide.
